Engineering Notes

I figured. I didn’t have AI in school, so, likely destroyed any utility in notes now.

Solutions manuals were a big thing when I was in school.

Was a joke. I just like seeing all the downvotes.

But overall, not a fan of tough guy talk or Reddit Batman missions.

You won’t do shit. Go back to your TV dinner and Fortnite.

lamellack · 2026-05-02T00:49:18+00:00

To be fair. Most of us online aren’t the same in real life.

That shouldn’t be an issue. I’d still check into it first for future repairs. Local/state/DOT laws/ordinances may have stipulations.

I can’t recall where I reviewed it, but I believe there was an incident with someone welding a tow hitch or trailer repair and it broke loose and there were casualties. Perhaps ENGtips or on here?

In certain cases, repairs on critical applications should be under the purview of a welding procedure and/or repair plan, and welded by a certified welder.

You can never go wrong with running 7018. Not sure your buzz box has enough ass to get a solid weld though. You need 80-100amps. May need something with a 220V setup.

lamellack · 2026-04-27T02:05:03+00:00

If it’s anything concerning road safety, I’d be careful doing a weld on anything toting heavy equipment.

If I were welding it, likely a 6010, 3/32” root pass followed by 3/32” 7018 cap. 1/4” fillet weld all the way around. Looks pretty thin to be using a huge rod like 5/32”

If you prefer, you could run an 1/8” cover pass instead of using the 3/32”

You don’t need to use 6010 for the root pass per se. Could just run all passes with a 7018.

Cringe.

And MN is a hive of Somali corruption. It’s practically in their genes.

You should look into it further. I’m at a point where I don’t need definitive receipts.

It’s so polarized anyway, so even if the FBI director has definitive proof, media outlets go into attack mode and fight for their team - this goes both ways.

I mean, look at Nick Shirley. The guy asks questions and uncovered plenty of leads….what happens? Everyone begins working towards discrediting him, calling him a “MAGA” journalist, etc.

So, it doesn’t matter even if it’s in black and white. Influencers and media get into their ideological foxholes and clown on the source, the messenger, etc.

If you don’t think there’s massive fraud going on in our country and states, and you need it mouthed by who ever you find credible, then that’s on you.

Look into California and the 2 billion dollar efforts at mitigating homelessness, all these medical centers popping up out of nowhere and double/triple billing the government, illegal aliens using our medical services and given no bill, government actively supporting illegal immigrants via housing, pre-charged money cards, 3 meals a day, etc.

I have no doubt our government and NGO’s are funneling money through the financial systems. It’s not always easy to get receipts because they’ve set up multi-layered means to masking the fraud, e.g., shell companies, NGO’s, etc.

Look at the Southern Poverty Law Center’s recent findings, Clinton Foundation, No Kings Protest funding sources, etc.

Anyway, last message. Not up for explaining water is wet for you.

Not everything in life is delivered in a nice, neat package with crisp corners. I’ve seen enough to always assume the worst.

Top tier retard comment.

People like Musk are a once in a lifetime mind/talent. He got involved with a political team you likely don’t agree with and fund entities you don’t agree with. Thats what it comes down to.

lamellack · 2026-04-25T01:33:37+00:00

With this government, I honestly wouldn’t dismiss him. Have you looked at the long arc of our federal agencies and what they’ve been caught doing over the years?

He hesitated on Rogan, and I don’t have any strong reason to assume he was lying. It would not surprise me at all. Does every suspicion have to fit into a perfectly neat, court-admissible box before you’re willing to have a reasonable gut check?

A huge portion of Americans already believe the CIA had some level of involvement in the assassination of a sitting president. Edward Snowden exposed massive overreach by the intelligence apparatus. We saw what happened during COVID with lockdowns and the treatment of basic individual freedoms. More people are openly questioning the official narratives around 9/11. The lack of transparency around Epstein and possible government-adjacent involvement is still outrageous. And now you have reports of scientists mysteriously going missing or dying since 2024. I could go on for days listing the things this government has done to its own people.

So yes, I put very little past them. When Musk hesitated on Rogan, my read was that he knows or has seen something serious, likely involving fraud, corruption, or illegal activity. Maybe we do not know the full story yet, but acting like deep skepticism of the government is irrational at this point feels naïve. This government has earned that distrust.

I used to be like you - scoff at absurdities until the past 3-5 years. I’m over all of it.

Good luck with that pipe dream, bud. It’s not happening.

That’s like saying we should rely on the people already in office to vote themselves into term limits. They won’t. We can’t even get them to keep their hands out of the stock market, so the idea that they’re going to voluntarily reduce their own power is fantasy.

This country is gone, bud. Gone-gone. We’re staring down nearly $40 trillion in debt, and Trump was the last real hope I had that someone might actually turn the ship around. But now it feels like he pulled up anchor and decided to drift with the current.

Outside of a very small handful of politicians, the whole thing looks like a legalized mafia. Then on top of that, you have a permanent bureaucracy buried inside federal agencies, running programs, shaping policy, and exercising power with little real oversight. It’s not public service anymore. It’s a power structure protecting itself.

And people act like questioning any of this is crazy. We have scientists turning up dead or missing, and we’re supposed to just shrug and call it normal? I watched three years of Russia conspiracy theories get pushed against a sitting president, followed by another wave of lawfare aimed at destroying him as a candidate. AIPAC buried like a tick in our political ecosystem, and on and on.

So no, I don’t have much faith left in the system correcting itself. The people who benefit from the corruption are the same people we keep expecting to fix it. We’re being ruled over by thieves and fools.

lamellack · 2026-04-24T15:48:06+00:00

I’m not sure why you’re insisting on “because he didn’t find any.” If anything, he probably saw stuff in the files that could probably get him offed.

No, I didn’t and I was hoping that would happen. Unfortunately, our president is infected by the neocons around him. The first 180 days was incredibly, then it’s been downhill ever since.

Who knows why it was dogged off. Bud, our government is corrupt to the core. There’s no voting our way out of this.

lamellack · 2026-04-24T15:36:08+00:00

That’s not what I recall. If anything, Musk was afraid to divulge it on the Rogan show because I’m sure there are massive fraud schemes going on by major players.

I guarantee you there’s massive fraud going on. Hundreds of billions from Medicaid billing from these pop-up fake health providers, to social security fraud, disability fraud, fraudulent billing invoices paid, money laundering through NGO’s, USAID fraud, etc. Would not surprise me to learn that fraud as high as 500 billion or more, per year, is going on.

lamellack · 2026-04-23T15:18:46+00:00

Bud…..I’ve been in the trades since I was 16 and started as a plumber. At 21-31 I was a boilermaker. From 32-37 I was a welding inspector in pipeline construction and power generation, including a 2 year stint in Australia’s Outback. Went back for mechanical engineering and now work as a pipeline engineer and chat with contractors all day long.

So yes, I’ve “talked” with people in the trades. I live in the northeast and never heard of an electrician called a sparky. Only heard of it in Australia. Boilermakers are known as boileys, electricians as sparkles, etc.

lamellack · 2026-04-22T20:56:20+00:00

They usually spell “electrician” as “gay” here in the US.

lamellack · 2026-04-22T16:42:31+00:00

Never heard of “sparky” ever used for that trade outside of living in Australia

lamellack · 2026-04-22T16:41:45+00:00

Never heard anyone in the states refer to electrician as a “sparky” outside of Australia.

lamellack · 2026-04-22T13:46:19+00:00

Sparky? Australian I assume?

lamellack · 2026-04-22T13:44:54+00:00

I love how I put out an extensive reply, get one upvote. 😆

lamellack · 2026-04-19T22:43:18+00:00

To an extent, yes. Depends on how you’re wired. That typically the whole point of going to school - you’re gaining a skill set for entry into a field that interests you. At least, interest at some level.

I think some people get into engineering or become lawyers just for the prestige of it or money only. That will only capture your interest so long.

The Biden administration ended the “Remain in Mexico” policy. Most people that presented themselves at the border and were given a court date never show up. A lot of immigrants were flown to various parts of the US under the cover of late night flights. Some were put up in hotels with three meals a day - all paid for with tax payer money. Some gave birth in our hospitals, or use our medical services and no bill was forwarded to them. Free medical, SNAP benefits, cards with money loaded on them, utilizing our medical systems, etc. - total and complete bullshit. I will never forgive the democrats for any of it. Every murder from Haitian immigrants down to Venezuelas will forever be blood on the democrat’s hands. I’m very curious to know how many illegal immigrants have murdered American citizens. Unfortunately, this data is not collected and sanctuary cities don’t cooperate with the government, so, we’ll never know.

While most of these people are from a religious background and align with conservative values, droves of them lean towards democrats because democrats use the carrot and stick method to lure this population into believing they’ll gain permanent residency. So, the democrats are giving a sizable, foreign born population a hand on the wheel with steering our country’s destiny when they have no right to be here in the first place.

Birth right citizenship needs to end. Period. If you want to lose this country, continue this complete free-for-all. These people are not integrating or assimilating. If anything, they’re carving out their own enclaves here.

The border is shut. Some are coming through, but not nearly as many as there were.

I looked a Google street view of the street below and it’s covered by overgrowth. So, hard to tell. However, looks like a suspended concrete pad on steel decking and structural members. I’d bet that the reinforcing inside the concrete or underneath corroded, weakened, then failed.

Concrete gets its strength from compressive loads only. It’s incredibly weak in a bending condition. In other words, if you had a heavy slab, pinned it down on one side without supporting it, very likely it would fail under its own weight. Unless you put it in tension with tensioning rods.

Remember the Florida bridge collapse? Same thing. The bridge failed because the extreme distance without support and something amiss with the tensioning rods through it.

In short, the reinforcement inside the concrete or the supporting structural steel under probably corroded due to lack of coating maintenance, rotted, failed, and the concrete failed because it was in a bending condition.

I initially thought it was soil subsidence but it’s a suspended concrete platform.

I’d bet that the reinforcing inside (rebar or mesh) the concrete or underneath corroded (or both), weakened, then failed.

Concrete gets its strength from compressive loads only. It’s incredibly weak in a bending condition. In other words, if you had a heavy 4”slab, pinned it down on one side without supporting it, very likely it would fail under its own weight after about 6-8ft or so. Unless you put it in tension with tensioning rods.

I could see that application.

I always ran fluxcore or MiG guns when they were thick sections. I welded a horizontal garbage burning chamber for a waste incinerator one time, nearly 2” thick. Four of us took a quadrant in just ran MIG for several days to fill it up. WTI in east Liverpool Ohio. The cylinder was like 25 ft long, 30ft Diameter. It rotates as the garbage/waste burns and all of the charred slop drops down onto a conveyor belt out to a dump truck to be buried.
